Roush Dual Rear Exit Exhaust System
Improve the power, fuel efficiency, and sound of your 2004-2008 F-150 with the ROUSH Dual Rear Exit Exhaust Kit. Referred to as "legal," this exhaust system generates a louder, throaty-sound, without exceeding legal sound level limits.
The mandrel bending process used for the tubes of this system maintains a consistent inside diameter through the bended area. This method allows for a significant increase in flow over stock / serrated-bent pipes. Due to this increased efficiency, both latent power and fuel efficiency are realized.
This F-150 exhaust system has T-304 stainless steel mufflers, providing resistance to corrosion and staining. The mandrel-bent tubing is manufactured out of aluminized steel. This system works with the 2004-2008 F-150 4x2 and 4x4 trucks (4.6L / 5.4L) in the SuperCab w/ 6.5' box and SuperCrew w/ 5.5' box body styles.
